l 0 all whom it may concern:

Be it known that I, 'Sonnn JENSEN, a citizen of the United States, residing atLos Angeles, in the county of Los Angeles and State of California, have inventednew and useful Improvements in Pencil-Sharpeners, of which the following is a specification.

This invention relates to pencil sharpeners of the. type adapted to be mounted upon a pencil and of the general classlofpencil sharpeners such as set forth in my prior U. S. Letters Patent No. 965,907, granted August 2, 1910, and 1,130,294, granted March 2, 1915,

It is the object of the presentinvention to provide an .improvedpencilsharpener of this type which .will form a pencil'point guard when the pencil is not in use, and

which may be shoved up upon the pencil to uncover the point thereof when the pencil is to be used. When the pencil is to be sharpened it is only necessary to slide the sharpener down along the pencil,'and .it is not necessary to remove the sharpener from the pencil when the sharpener is to be brought into operative position.

The invention will be readily understood from the following description of the accompanying drawings, in which- Figure 1 is a perspective view showing the pencil sharpener upon a pencil in position to permit use of the pencil.

Fig. 2 is a similar view showing the pencil sharpener moved down to form a point guard for the pencil. V

Fig. 3 is a similar view showing the sharpener in operative position for sharpening the pencil point.

Fig. 4 is a top plan view of the pencil sharpener. v

Fig. 5 is a side elevation of the same.

Fig. 6 is a longitudinal section on the line 6-6 of Fig. 4.

Fig. 7 is a bottom plan view of the pencil sharpener.

Fig. 8 is an end view of the same.

Fig. 9 is a perspective view of the cutting blade.

The sharpener is shown mounted upon the pencil 1, the sharpener consisting of a substantially tubular structure 2 formed of sheet metal. The side edges of the sheet metal blank are brought substantially to gather so as to form the longitudinal slot 3, and the top of the tubular structure is provided with a slot 4 adjacent the forward end thereof, which. at its rear end termigroove 14 for the cutting blade.

nates in a lip 5 projectin forwardl into slot 4. This lip is provided with 2L3; up-

turned front end 6 and the arrangement of the lip provides a spring member adapted toreinovably retain the cutting blade of the sharpener in position. 1 t

In front of slot 4 the tubular structure forms a cross strip 7 beneath which the cutt ng blade extends so as to rest upon the portlons 8 of-the tubular structure at the sides of slot 4. The tubular structure beyond the cross strip 7 is recessed inwardlv from the end of said structure as shown at 9. The portion of said tubular structure at one side of the recess 9 forms asupporting extension 10 beneath which extends the out forming the tubular structure, said lateral extensionbeing bent around and over the edge of the tubular structure at the recess 9. This portlon 11 of the tubular structure is, preferably, tapered toward its forward,

end, as clearly shown in Fig. 8, so as to terminate in the opening 12 through which the point of the pencil extends when the pencil is in position for use. The portion of the tubular structure forming the supporting extension 10 is, preferably, reversely bent beneath the same, as shownat 18 in Fig. 8, in order to provide the lon itudinal I The cutting blade is mounted with its cutting edge 15 extending along recess 9 in position to lie adjacent the end of the pencil projected through opening 12. I

The blade comprises a shankportion 16 underlying cross strip'7 and a rear extension 17 resting upon shoulders 8. The rear end of this extension is provided "with a notch 18 adapted to engage the upturned end. 6 of the spring retaining lip 5. The cutting blade projects forwardly from shank 16 so as to be received in the groove 14 and is, preferably, downwardly bent relative to said shank so as to conform to the desired taper arranged to be provided at the pencil point.

It will be understood that the cutting blade is retained in position by spring lip 5, and when it is desired to insert a new blade it is only necessary to bendthe lip upwardly so as to disengage the same from the extension 17 of the cutter, and the latter may then be readily removed by withdrawing. it from groove 14 and from beneath cross strip 7.

In operation the sharpener is placed upon the end of a pencil, the sides of the blank so as to cover the, point and form a protector therefor, as clearly shown in Fig. 2. hen the pencil is to be used the sharpener is slid along the pencil so as to uncover the point, as shown in Fig. 1. v

' When it is desired to sharpen the pencii it is only necessary to hold the sharpener against rotation by one hand and rotate the pencil relative to the sharpener by the other hand so as to cause the blade of the cutter to impinge with a cutting action against the wood at the pencil end.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is:

1. In a pencil sharpener, a tubular memher having a tapered slotted forward end, a spring tongue projecting into the slot in said forward end, a plate positioned on the forward portion of said tubular member and retained in place by said spring tongue, an inclined finger projecting downwardly from said plate and positioned at one side of the slot in the tubular member and said finger being beveled on one side to form a cutting edge.

2. A pencil sharpener including a tubular structure positioned upon a pencil, a'cutter at the end of said tubular structure and comprising a plate and an inclined finger proj e'cting downwardly from said plate, said finger having a cutting edge extendinglengthwise ofsaid pencil, said tubular structure and pencil being arranged for relative removable cutter inserted beneath said cross strip and positioned at said end recess which removable cutter comprises a plate, an inclined finger formed integral with and projecting downwardly from said plate, one side of which finger is beveled to form a cutting edge. I

4. A pencil sharpener including a tubular structure having an end recess, a slot spaced fromsaid recess to form a cross strip, a removable cutter inserted beneath said cross strip and positioned at said end recess, said cutter comprising a notched .plate and an in clined finger projecting downwardly there from, one side of which finger is beveled to form a cutting edge,-and a spring lip projecting into said slot and arranged to engage in the notch in said plate for retaining the same in position.

In testimony whereof I have signed my name to this specification.
